…inder #25) Folds every closed decision on map #11 into one ready-for-agent spec in the M5 mold: support tiers, the Linux seam fills by tier, the full Capabilities table with Linux columns, injection/hotkey/identity/runtime/audio/packaging/ permission/desktop sections, the platform-conditional UI list, a real-hardware verification pass and a ticket index. Gathers ADRs 0007-0014, the six Linux research docs and scripts/bench_cpu_stt.py from their wayfinder/* and research/* branches so the spec's links resolve, and folds the branches' CONTEXT.md glossary edits (Support tier now says "no overlay" on Portal per ADR 0014).

Inline comments:
In `@docs/adr/0007-linux-injection-follows-the-support-tier.md`:
- Around line 17-35: Clarify the ADR’s degraded Wayland behavior for both Portal
and Reduced when neither ext-data-control-v1 nor the Clipboard portal is
available: specify whether each tier uses the type-only ladder for that run and
whether typing becomes the default automatic action or remains available only
through the explicit “Type it” override, keeping the no automatic paste-to-type
fall-through rule consistent.
In `@docs/adr/0008-linux-hotkey-capture-no-evdev.md`:
- Around line 13-17: The portal permission contract must vary by the selected
input or clipboard mechanism: update
docs/adr/0008-linux-hotkey-capture-no-evdev.md lines 13-17 to require
RemoteDesktop only when needed, align the mechanism table and required-grant
calculation in docs/specs/m6-linux-port-spec.md lines 82-84, and remove the
claim of a uniform Wayland grant flow in CONTEXT.md lines 145-157.
- Line 9: Fix both Markdown lint violations: in
docs/adr/0008-linux-hotkey-capture-no-evdev.md at line 9, escape or label the
leading “#19”; in docs/research/linux-desktop-integration.md at line 177, add
the missing Route cell to the GNOME Wayland row.
In `@docs/adr/0009-linux-app-identity-desktop-id.md`:
- Around line 7-10: Update the desktop-file discovery specification to include
$XDG_DATA_HOME/applications, defaulting to ~/.local/share/applications when
unset, alongside $XDG_DATA_DIRS/applications and Flatpak exports. Define a
deterministic search precedence with the user application directory taking
priority, and deduplicate entries by desktop-file identity so user-installed
applications and Cadent’s entry resolve correctly.
- Around line 36-44: Update docs/adr/0009-linux-app-identity-desktop-id.md lines
36-44 to ensure Portal does not advertise per-app overrides unless focused-app
identity is available, either by documenting a non-KDE identity source or
disabling the capability for unsupported sessions. Update
docs/specs/m6-linux-port-spec.md lines 31-34 to remove the unconditional
Portal-wide override promise, and align CONTEXT.md lines 127-135 with the
resulting capability matrix.
In `@docs/adr/0010-linux-two-gpu-packs-vulkan-cleanup.md`:
- Around line 12-32: Align docs/research/linux-gpu-runtimes.md and stale runtime
comments with ADR 0010 and the Linux specification: use CUDA-enabled Parakeet
and RTLD_LOCAL preloading rather than CPU-only execution or RTLD_GLOBAL. Add
Linux validation covering each pack independently and both together in one
process, asserting faster-whisper uses CUDA, Parakeet’s session.get_providers()
includes CUDAExecutionProvider, and the CUDA 12/13 libraries do not interfere;
document RTLD_LOCAL’s symbol visibility and same-soname loading behavior
accurately.
In `@docs/adr/0011-linux-ships-tarball-appimage-aur-not-flatpak.md`:
- Around line 56-63: Update the documentation at
docs/adr/0011-linux-ships-tarball-appimage-aur-not-flatpak.md lines 56-63 to
state that the current absolute AppImage path is resolved before writing desktop
entries and used for both Exec= and TryExec=, rather than relying on $APPIMAGE
expansion. Apply the same correction at docs/research/linux-packaging.md lines
168-171; both sections should consistently describe writing the resolved path.
- Around line 33-42: The ADR and research recommendation are inconsistent about
the Linux runner and glibc floor. In docs/research/linux-packaging.md lines
239-247, update the recommendation to ubuntu-24.04 with glibc 2.39, or
explicitly label the ubuntu-22.04 guidance as superseded historical analysis;
describe the September 17, 2026 runner deprecation as scheduled. The ADR site
docs/adr/0011-linux-ships-tarball-appimage-aur-not-flatpak.md lines 33-42
requires no direct change.
In `@docs/adr/0013-linux-portal-transport-is-jeepney-not-qt.md`:
- Around line 13-18: Declare Jeepney as a Linux-only dependency in
pyproject.toml and regenerate uv.lock so the package and metadata are locked. In
the ADR text, update the router reference to the fully qualified class
jeepney.io.threading.DBusRouter.
In `@docs/research/linux-desktop-integration.md`:
- Around line 171-177: In docs/research/linux-desktop-integration.md lines
171-177, mark the LayerShellQt and XWayland routes as superseded pre-decision
research per ADR 0014; in lines 215-224, replace or mark the app_picker=False
recommendation to align with ADR 0009’s installed-app discovery; in lines
231-232, replace or mark the no-permission recommendation to align with ADR
0012’s request_permission() behavior.
In `@docs/research/linux-packaging.md`:
- Around line 179-184: Update the desktop-entry installation wording in the
conventions section to use $XDG_DATA_HOME/applications for per-user entries,
defaulting to ~/.local/share/applications, and reserve /usr/share/applications
for system-wide packages. Align the terminology with ADR 0011 while retaining
the other entry requirements.
In `@docs/specs/m6-linux-port-spec.md`:
- Around line 305-308: Separate Hyprland and stock Sway validation in
docs/specs/m6-linux-port-spec.md: test GlobalShortcuts on Hyprland, but require
stock Sway to validate hotkey-unavailable with no permission prompt. In
docs/research/linux-input.md, split the permission table so Hyprland is not
grouped with stock Sway.
In `@scripts/bench_cpu_stt.py`:
- Line 186: Update the p95 calculation in the benchmark script to use an
interpolating estimator between the appropriate ordered samples, matching the
documented methodology in the benchmark research. Regenerate the published
benchmark tables with the corrected estimator.
- Around line 239-244: Update main() around the subprocess.run failure handling
to track when any benchmark row fails instead of only continuing. Preserve
reporting of failed rows and partial results, then return or exit with a nonzero
status after processing all engines, models, and devices whenever a failure was
recorded; successful complete runs must retain status zero.

Addresses the CodeRabbit round on PR #29: - ADR 0007 / spec: the dropped-paste-rung case applies to either Wayland tier; ("type",) is the run's only rung, not a fall-through. - ADR 0008 / spec / glossary: permission_granted() requires the RemoteDesktop session only where the run's typing/paste mechanism rides it, so Hyprland (GlobalShortcuts, no RemoteDesktop backend) never faults forever. Still one "portal" value. - ADR 0009 / spec / glossary: desktop-file discovery searches $XDG_DATA_HOME/applications first, then $XDG_DATA_DIRS, then Flatpak exports, first match by id wins; Portal identity adds wlr-foreign-toplevel-management for wlroots and drops per_app_overrides for a run with no toplevel protocol. - ADR 0011 / spec: the autostart Exec/TryExec is the resolved APPIMAGE path (desktop entries expand no variables); user entries go to $XDG_DATA_HOME/applications. - ADR 0013: jeepney.io.threading.DBusRouter. The dependency itself lands with the skeleton ticket (#33), not this docs PR. - Spec §12: Hyprland validates GlobalShortcuts on wlroots; stock Sway is the hotkey-unavailable negative case. - Research docs: a "research snapshot" banner naming the ADRs that supersede each doc, instead of rewriting historical findings. Fixed the missing table cell in linux-desktop-integration. - Bench: doc describes the nearest-rank p95 the script actually computes (not re-run); the driver now exits nonzero after printing a partial table; B905 zip(strict=True).

Summary
Resolves wayfinder ticket #25 on map #11 — the destination of the Linux port wayfinding.
docs/specs/m6-linux-port-spec.md(Status: ready-for-agent, M5 mold): scope/out-of-scope, the three-tier support model + target×session validation matrix, the Linux seam (cadent/platform/linux/, jeepney), the eight-seam fill table by tier, the fullCapabilitiestable with three Linux columns, per-decision sections (injection, hotkeys, identity, runtimes, audio, packaging, permission copy, tray/overlay/DesktopEnv), the platform-conditional UI list, a fourteen-item real-hardware verification pass, and an eleven-row ticket index.docs/research/linux-*.mdandscripts/bench_cpu_stt.pyfrom theirwayfinder/*/research/*branches so the spec's links resolve (docs only — nothing else from those branches).CONTEXT.mdglossary edits together;Support tiernow says "no overlay" on Portal per ADR 0014.changelog.d/25.docs.md(non-rendering).The one unresolved fog item on the map — IME / international input interplay — was never researched, so the spec carries it as verification item §12.8 rather than a decision.
